Research and Testing to Accelerate Voluntary Adoption of Automatic Emergency Braking (AEB) on Commercial Vehicles

This report describes barriers to truck fleets’ voluntary adoption of automatic emergency braking (AEB), and actions that may mitigate or eliminate these barriers. The report recommends approaches that the Federal Motor Carrier Safety Administration (FMCSA) could take to accelerate voluntary adoption of AEB technologies. It rates these approaches based on potential resource and time requirements, potential impacts on voluntary AEB adoption, and potential for a recommended action to fail. It also outlines one potential core strategy for reaching 90 percent adoption for new heavy-duty vehicles, though other strategies may also be feasible depending on FMCSA resources and priorities. While there does not appear to be a feasible roadmap to achieving 90 percent voluntary adoption for medium-duty vehicles, the strategies for the heavy-duty segment may still be viable for some medium-duty applications. Once some of the technical barriers with medium-duty vehicles are resolved, these market strategies may boost voluntary adoption within certain medium-duty market segments, though it remains unclear whether a 90-percent take rate is achievable. This report will help industry stakeholders understand the issues fleets have experienced during AEB adoption and what tools fleets require to see AEB as an economically attractive option for their new vehicle purchases.
